Project kai/ diy dragon deck/ carvon dual hub motors trucks/ space battery/ dual vesc/ nunchuck

Nooooo! Went for a ride about 6 miles and power just shut off something must have came loose from battery. Going to have to take it apart again today.

Now my battery is powering up againā€¦ cant figure out whats wrong when it works lol

Ainā€™t that always the case? Happens all the time with one of our carsā€¦

So my space cell shuts off when my volt meter reaches 30%. Is that normal? I am only getting about 8 miles per charge. Any thoughts on this guys? Thanks

Man I hope thatā€™s not normalā€¦You should be able to go way further than that!

My motor wires came loose even with them shrinked wrapped and that caused this right?

@chaka i am going to order another vesc from you. Can i send this one in for repair as well? If so what is the cost on something like this? Or am i better off buying new ones then repairing. edit ordered

Does it melts your DRV8302? seems like it.

Yeah my drv8302 is melted

Good luck man, I know it sucks but things especially donā€™t seem to be going your way :sob: :frowning:

That sucks @kaiā€¦Was it a bullet junction or did a wire come unsoldered? Iā€™ll certainly be hot glueing mine anywhere and everywhere I can after seeing this.

Hello @kai

Thank you for your order! You can send that unit to me, it should be salvageable. At worst we can swap your good components over to a fresh PCB and deduct the cost of the components saved towards a ā€œbare bonesā€ VESC

Ok thanks chaka. May be a bit before o send it so i will contact you about it later. Thanks cmatson t.t @psychotiller yeah all three seemed to be loose from the connectors. I think 2 came completely out. I just did a crappy job on the individual connector shrink wrap before shrink wrapping all three wires together. The other motor wires seem solid. Learning experience thoughā€¦ my first build. I did get it up to 25mph according to gps before the wires came loose! I then decided i needed to change my bushings.

What current limiting do you have set in the vesc?

I assume those hubs ask for lots of AMPS. This could be causing major voltage sag and then the VESC (or space cell) is shutting down because of low voltage.

You may want to limit motor current a bit more.

It wasnt set right. I set it to 30 amps on both and my motor wires shorted my vesc. I will update on the battery when i am up and running again. Thanks for the help

ming if I ask you how does this fabric transfer work? Did you bought a fabric with a drawling and transferred it to the wood? or did you glue it to the board? edit: never mind, got it, applied the fabric and them fiber glass on top of itā€¦

Yeah. I used west system 105 resin and the 207 hardener. The 207 dries super clear so ideal for something like this but takes a full week for full cure. You dont need fiber glass. I added it to increase strength. All you need ti do is add resin to sanded wood. Put fabric onā€¦ stretch fabric flat over board and add more resin to saturate. Add fiberglass over that while it is still wet if you want to add more protection or decrease flex.

Hey chaka. How far behind are you guys on vesc production? You guys send email conformation when it sends?

We do! Sometimes they end up in your spam folder. Give me your order number and I will let you know where you are at in line.

Edit: I found your order. You are included it he current batch of builds. We should have it have it the post on Monday. If you want to bring the other vesc to life send it to:

Ok thanks chaka. Not sure this vesc i burnt is worth saving. I tried replacing the chip myself and ruined it lol. Worth the experience for me though. Now i know. I will just order 2 new ones when i start my next build later in the year.

Donā€™t throw it away, you can use the mosfets to make a few anti-spark switches.
